Nova in Scutum

NOVA SCUTI 2005 Number 2
V477 SCUTI discovery magnitude 10.6 (photographic)

Position(2000): R.A. = 18h 38m 42.93s Dec = -12o 16' 15.6"
Field of view 45 x 60`

Spectra taken Oct. 15.75 UT by R. K. Das, N. M. Ashok, and D. P. K. Banerjee, Physical Research Laboratory (PRL), Navrangpura, India, and by M. Fujii, Ibara, Okayama, Japan, on Oct. 16.43 UT indicate a classical nova early in decline.

A nova, occurs when a normal star orbits a white dwarf star.
Matter accretes in a thin layer on the surface of the white dwarf (shed from the normal star) and eventually ignites in a thermonuclear explosion under degenerate conditions.
This blows a thin surface layer off into space, causing a large rise in light output from the binary system.
